And I know a lot of guys would be against this but If I had to do it over again, I would run my pipe 5- 6" diameter and put a damper on it to help control the draft.
The one I have on Frank is a 4" diameter pipe but I always run it full open, on occasion I have closed it it for a minute to drop temps if they get too high.
I would use a configuration like this 4 or 5" closed 5 or 6" open, this takes the guess work out of proper sizing.The baffle would be like a washer.
